Abstract: An imaging system and methods are presented for determining a size of a viewed object through a monocular endoscope. The system includes an imaging device mounted on the endoscope, at least one light source disposed in a fixed position relative to the imaging device, and a processor configured to receive input from the imaging device and analyze at least one of shadow effect from the light source, structured lighting provided by the light source, multi-point illumination including the light source, time-of-flight involving light pulses from the light source, and lateral color aberrations from the light source to determine the size of the viewed object.

Abstract: A fluid management system may include an inflow pump providing a fluid inflow to a medical device, at least one pressure sensor, and a controller configured to receive pressure signals from the at least one pressure sensor, the pressure signals corresponding to a system pressure within the fluid management system. The controller may be configured to detect which one of a plurality of medical devices is fluidly connected to the inflow pump based on the pressure signals from the at least one pressure sensor and an rpm of the inflow pump.

Abstract: Systems and methods related to combing multiple images are disclosed. An example method of combining multiple images obtained by an endoscope includes obtaining a first input image formed from a first plurality of pixels, wherein a first pixel of the plurality of pixels includes a first characteristic having a first value. The method also includes obtaining a second input image formed from a second plurality of pixels, wherein a second pixel of the second plurality of pixels includes a second characteristic having a second value. The method also includes subtracting the first value from the second value to generate a motion metric and generating a weighted metric map of the second input image using the motion metric.
